Formula Para Calcular Calorias Para Bajar De Peso

Losing weight requires creating a caloric deficit, which means consuming fewer calories than your body burns. This calculator helps you determine your daily calorie needs and create a healthy deficit for weight loss.

How to calculate calories for weight loss

The process of calculating calories for weight loss involves several key steps:

Determine your Total Daily Energy Expenditure (TDEE)
Calculate your maintenance calories
Create a caloric deficit by eating fewer calories than your TDEE
Monitor your progress and adjust as needed

Using our calculator, you can quickly determine your TDEE based on your age, gender, weight, height, and activity level. From there, you can set a realistic calorie target for weight loss.

The formula explained

The formula used to calculate calories for weight loss is based on the Total Daily Energy Expenditure (TDEE), which accounts for both your Basal Metabolic Rate (BMR) and your activity level.

BMR Calculation

For women: BMR = 655.1 + (9.563 × weight in kg) + (1.850 × height in cm) - (4.676 × age in years)

For men: BMR = 66.47 + (13.75 × weight in kg) + (5.003 × height in cm) - (6.755 × age in years)

TDEE Calculation

TDEE = BMR × Activity Factor

Activity factors:

Sedentary: 1.2
Lightly active: 1.375
Moderately active: 1.55
Very active: 1.725
Extra active: 1.9

The recommended calorie deficit for weight loss is typically 500-750 calories below your TDEE. This will result in about 0.5-1 lb (0.23-0.45 kg) of weight loss per week.

Important Notes

Individual results may vary based on genetics, muscle mass, and other factors. Always consult with a healthcare professional before starting any weight loss program.

Worked example

Let's calculate the calories needed for a 30-year-old woman who is 165 cm tall, weighs 60 kg, and is moderately active.

Step 1: Calculate BMR

BMR = 655.1 + (9.563 × 60) + (1.850 × 165) - (4.676 × 30)

BMR = 655.1 + 573.78 + 303.25 - 140.28

BMR = 1,391.85 kcal/day

Step 2: Calculate TDEE

Activity factor for moderately active: 1.55

TDEE = 1,391.85 × 1.55 = 2,149.6 kcal/day

Step 3: Create a calorie deficit

Recommended deficit: 500-750 kcal below TDEE

Target range: 1,649.6 - 1,899.6 kcal/day

This woman should aim to consume between 1,650 and 1,900 calories per day to lose weight at a healthy rate.

Tips for successful weight loss

Creating a calorie deficit is just one part of successful weight loss. Here are some additional tips:

Focus on whole, nutrient-dense foods rather than processed foods
Stay hydrated by drinking plenty of water throughout the day
Get regular exercise to complement your diet
Track your food intake to ensure you're staying within your calorie target
Be patient - weight loss takes time and consistency
Get enough sleep - poor sleep can affect your metabolism and hunger hormones
Manage stress - chronic stress can lead to weight gain

FAQ

How many calories should I eat to lose weight?

The number of calories you should eat to lose weight depends on your TDEE and your target weight loss rate. Our calculator can help you determine your TDEE, and the recommended deficit is typically 500-750 calories below your TDEE.

Is it safe to create a large calorie deficit?

Creating a very large calorie deficit (more than 1,000 calories below your TDEE) can be unsafe and may lead to muscle loss, nutrient deficiencies, and other health problems. It's important to create a deficit that is sustainable and healthy for your body.

How long does it take to see results from a calorie deficit?

The time it takes to see results from a calorie deficit depends on several factors, including your starting weight, your target weight loss rate, and your overall health. Generally, you can expect to see noticeable changes in about 1-2 weeks, with more significant changes occurring over several weeks or months.
